Not related to you" is not entirely accurate as some family members such as siblings are NOT disqualified parties, however, spouse, parents, grandparents, children, all lineal descendants are disqualified parties as are your plan administrators, investment advisors, and fiduciaries.

I've been planning on trying another investment soon but have limited cash on hand 10-20k and a low credit score (until last year, new construction wasn't doing very well and my income reflects that). 2)My family (Parents and Siblings) live overseas.  

B dies 10 years later. 35 years later D conveys the property to himself as life tenant with full powers, remainder to 2 siblings (E, F) as tenants in common. 10 years later, upon D's death, 50% of the property is conveyed 50% to E and 50% to 3 children identified in F's will (F having predeceased D). 10 years later, the heirs of E and the heirs of F convey the property 100% to G... a third party purchaser for value.

My dad passed away recently and left 3 properties to my siblings and I in a trust. 2 of the properties are multi-family rental units. 

I could have taken this project down by myself, however I wanted to bring a couple of my siblings into the deal.

I'm trying to anticipate anything going wrong with this 'sale of house' scenario: I was named the executor of my Mom's trust, specifically because my Mom said she didn't trust my only sibling. 

My dad has a house in the Philippines and I believe it has multiple properties on the land, each property owned by each of his siblings so he has one house on the land.

We don't mind buying into it as they can't just give it to us since they are retired and use the income for their expenses and we have another sibling not involved so gifting would not be fair.

You want each student who is party to the lease and who does not have sufficient credit history, income, or assets to qualify on their own, to have a guarantor (parent, grandparent, older sibling, etc).  

There's varying ages for how old a minor can be to babysit siblings.
